Not sure I understand your concern here. You will need some access to it for cleaning, even in a well run kitchen, things still managed to find their way in. In commercial kitchens, baffles are used to catch all the fat and grime. Not seen them on domestic extractions. They are easy enough to make.

This is from the BBC

Belgium is closer to Trevor than I am.

Why should they when a stern letter to the Daily Telegraph, or a badly informed one to the Daily Mail, will get policy changed to more fossil fuel burners and higher prices. Only got to see how a small group of right-wingers has got control of the EU climate committee this week to see what damage can be done. Don't let the better be the enemy of the best

Isn't an EPC to do with reducing energy usage, which has the side benefit that is also reduced CO2 emissions. I agree that the system is not perfect, but it has been around long enough that we know how it works.

Go to Trevor at cylinders2go (Telford) and mention my username and the forum Did me a good deal and it was delivered in a couple of days.

Why unfair? Those technologies do not generate power on their own.

Spend an extra hour in the car in the A30 and save yourself more disappointment. Out of interest, did you pay by credit card, though I am not sure if consequential damage is covered by Section 75.

Kw/h is thermal mass. And electric comes from unicorn farts (that was either @DamonHD or me said that over a decade ago, but neither of us remember who said it first, but happy to take credit for it, not as if I am walking The Fraud Path at the minute).

Look for a taper on the edges then.

Dimples down. It creates more surface to whatever it is bonding to. Actually I don't have a clue on those council slabs, but when we made tooling for concrete slabs, the edges had a slight taper on them so the slab realised from the mould easily. The slightly small face became the top. That face could have any texture you liked on it. Those slabs look like they are stamped out, hence a texture on both faces. Stamping, or high pressure moulding, allows for less water usage (just the correct amount), better filling of the tool, less waste, faster processing times (minutes rather than hours) and a more homogeneous product that takes up less manufacturing space.

Think that is a heathen thing. We feed our children, Tom Bawcock fed the whole village. Should have got Tesco to deliver, it is only 3 miles away.

With Cornwall being different again. It is Mousehole, so as long as a small child can roll a barrel of pilchards down it, then there is room for a campervan.

We have a Flora Day down here they do the Fury Dance on it.

I am sure you have seen this, about the width. https://www.gov.uk/guidance/public-rights-of-way-landowner-responsibilities No idea about height on the boundary, some buildings are the boundary, and after quite tall. Took this yesterday. Not much more than a metre wide in places.

While they can heat, or cool, the air by a few K, there is not much airflow though MVHR, so not much power into the room. Fitting them into ductwork is really for forced heating/cooling systems.

As @JohnMo says, more floor insulation. Once you know the total, worse case, heat losses, it is relatively easy to work out the pipe spacing. I cannot think of a good reason to go greater than 16mm tubes. I think 20mm is for very long runs and lots of tight bends. Check you can do the full loop with one length, you really only want joints at the manifold.

I have my microwave running and it is at 53 dB, it is 3 metres away. If I turn the radio on, which is about 1 metre away, the noise goes to 58 dB. Radio only 55 dB. So while I hate noise, it can be easily masked. With nothing on (so no rustling from clothes) my kitchen is at 11.5 dB, and it is quite windy outside today.

If it was at work, the the Health and Safety Act states that 'you are responsible for your own, and other peoples' safety'. I am sure there is a similar statement for doing work for people, vicarious liability is complicated though.

Was one down here, but not that recently. https://www.building.co.uk/news/hse-issues-boiler-warning-after-scalding-deaths/3092050.article

Because we have a mature democracy, that hates to make a decision.

Because they will, and are already doing so in some parts of the world. That came about from the old (late 1990's) subsidiaries. What was not foreseen, and reacted to fast enough, was the rapid drop in price if offshore wind and large scale solar. Because of this rapid drip, planning rules and grid connections are hampering the up take. Rather than piss about with subsidies/incentives, the government just needs to take planning restraints out of local authority decision makers (which they want to do). Money can be raised by increasing taxation on combustion technologies easily enough. I really don't understand why this is not happening.

Read this. https://www.aquaswitch.co.uk/blog/lcoe/ It gives a good insight to the problems.

You could coat it with a clear casting epoxy. The main problem is that epoxy is very good at crosslinking the polymers, which is what is wanted for strength, durability and stability, but makes it a bugger to stick other things to once cured.

Probably not an engineer. Probably Level 3 technicians at best. It seems odd that that to fit PV panels, though the MCS system, a qualified structural engineer has to sign of the roof structure, but to put quarter of a tonne of hot water above people needs nothing.
